I would like to use a Twitter API to post data from my website on Twitter. Can you help me with how to set up such an API?

In my dev account is only:
Application under review
To get started with Twitter APIs, you will have to wait for your developer account application to be approved. Check the email address associated with this account for updates. But I have not done anything yet?

Hi @Lust24_eu - in order for your developer account to be approved you will have to respond to the follow up email we sent you on 10/8/2018 asking for more information. You may want to check your Junk or Spam folders for this email. Once you have responded to this email, including as much detail as possible, your application will continue to be processed.
